Pound per square inch to megapascal (psi to MPa) conversion table shows the most common values for the quick reference. Alternatively, you may use the converter to convert any other values.
1 Psi = 0.00689475729 Megapascal
Psi is defined as 1 pound of force applied per square inch. It is the main pressure unit in United States and widely used in all kinds of applications. 1 pound per square inch (psi) equals to 6 894.75729 pascals.
Megapascal is a metric pressure unit and equals to 1 000 000 force of newton per square meter which is a pascal. 1 MPa equals to 10 Bar. Mostly used in hydraulic systems because of its high pressure ratings. The abbreviation is "MPa".
